Problem setting up satellite tracking amateur radio station

Hi I am a licensed ham, Vk3bzf and am attempting to set up my system for the purpose of tracking and Tx ing with low earth orbiting satellites (Leo’s). I have a the appropriate Yagi’s for 2m/70cm bands, the G5500 rotator, the gs232b, SatPC32 and ts2000. However despite having spent a number of hours trying to make it work, at present no success. The software won’t command the rotator to work. I would appreciate assistance. Best 73’s Peter Vk3bzf
